Specification forming part of Letters Patent No. 177.573, dated May 16,1876; application filed March 27, 1876.

. To all whom it mayconoern:

- Be it known that I, BENAMMI SELPH, of Lynchburg, in the county ofHighland and Stateof Ohio, have invented certain new and usefulImprovements in Rotary Scrapers; and

I do hereby declare that the following isa full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which forinpartof thisspecification.

The nature of'my invention consists in the construction and arrangementof a roadscraper, as will be hereinafter more fully set forth.

In orderto enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 isa plan view, and Fig. 2 a side elevation, of my invention.

The frame of myroadscraper consists of a metal bar, bent to form twocurved parallel side arms, AA, connected at their rear ends by across-bar, B,.all in one piece. The front ends of the arms A A areconnected by a bar,

G, fastenedthereto, and provided with a central eye, 0, -or otherdevice, for attaching the team. I D D represent two nearly-circularirons, between which thescrape'r E is fastened. These irons are providedwith radial arms D,

pivoted to the arms A of theframe, as shown. In the back edge of eachiron D, at or near 3 V the center, is'mado a notch, a, into which takesa bar, G, sliding upon the rear portions of the arms A, and pressedforward by a spring,

scraper can go on continuously by simply drawing the spring-bar andleaving it to return to the notches by its own action.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

, Thecombination, in a road-scraper, of the rectangular frame A B G,circular irons D D,

having notches a a in their rear edges, the

arms D, rigidly connected to the center of the irons D, thescraper-plate E, secured be tween the irons, and the sliding bar G,having thimbles which surround the bars A, and the flat spring b, allconstructed substantially as and forthe purposesherein set forth.

In testimony that I claim the foregoing as my own I afiix my signaturein presence of two witnesses.
